Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523384, here are decompositions:

3 + 31523381 = 31523384
37 + 31523347 = 31523384
157 + 31523227 = 31523384
163 + 31523221 = 31523384
223 + 31523161 = 31523384
241 + 31523143 = 31523384
271 + 31523113 = 31523384
331 + 31523053 = 31523384

Showing the first eight; more decompositions exist.
